I have a new installed Ubuntu 18.04 server system with kopano 8.6.81, user backend LDAP. If I try to create a new user via kopano-cli --sync or just login to webapp I found the following line in syslog:

Aug 24 09:40:44 charlieb kopano-server[28365]: /usr/lib/kopano/userscripts/createuser[28519]: Your system does not have the 'en_US' locale installed.
Aug 24 09:40:44 charlieb kopano-server[28365]: /usr/lib/kopano/userscripts/createuser[28519]: Please install this locale before creating new users.

That is a little bit strange to me because I have set /etc/default/kopano to


This surprised me more: In /usr/lib/kopano/userscripts/createuser I found this line:


What I didn’t understand: KOPANO_USERSCRIPT_LOCALE is set to de_DE.utf8, LC_MESSAGES is set to en_US.utf8 - why does this script use en_US as default value?

This is now more of cosmetic nature: In /usr/lib/kopano/userscripts/createuser.d/00createstore I found this line:

kopano-admin -v --utf8 --create-store "${KOPANO_USER}" --lang "${KOPANO_LANG}"

Is is not recommended to use kopano-cli? If I run that command by hand this way everthing works fine and I can login to webapp:

kopano-admin -v --utf8 --create-store "<my-login-I-wanted-to-test>" --lang "de_DE.utf8"
The selected option is deprecated in this utility.
Forwarding call to: `kopano-storeadm -h default: -Cn  <my-login-I-wanted-to-test> -l de_DE.utf8`.
Store GUID is 582815b2b5dd4f47a0f5d2f32b97e7a5

Ok, kopano-admin also tells me that it is deprecated. Just a cosmetic thing, nothing spectacular.

Have I misunderstood anything here and not configured properly? Or is the cause completely different?
